The Quail Ridge Reserve is part of the University of California Natural Reserve System and is located in Napa County on a peninsula at the southern end of Lake Berryessa. The reserve is composed of land owned by the US Bureau of Land Management, US Bureau of Reclamation, Quail Ridge Wilderness Conservation, California Department of Fish and Game, and UC Regents. The University NRS continues to expand on the reserve as private property owners become willing to sell parcels, thereby increasing the size of this amazing protected wildlife and ecological study site.

Vegetation on Quail Ridge consists primarily of mixed oak woodland, riparian, native and non-native grasslands, and chamise chaparral.

The illustrated beetles and species and family list in this book are the product of a beetle survey conducted on the reserve. Beetles were collected by black light at the reserve field station and in Decker Canyon, on flowering vegetation, under logs and other harborage, and along roadsides during daytime and evening hours and reared from logs.
